Appncaion nea Ju1y16,1s9s. serrano. 636,100. Numdam To @ZZ whom it may concern:

Be it known that I, JOHN T. Moniiow, electrical engineer, of Great Falls, in the State of Montana, have invented Vcertain new and useful Improvements y in 'Apparatus for Electrolytic Processes, of which the following is a description, referring to the accompanying drawings, which forni part of this specification. t I

The invention relates particularly to solution-stirring apparatus applicable to electrolytic tanks for refining metals.

It is well known that a vigorous circulation of the electrolyte in the refining or plating tank is a desirable feature, as it tends to produce smooth and even deposition upon the cathode.l vVith high densities of current it "Wis in convenientand expensive te Vobtain a vigorous circulation between the electrodes by means of a constant inflow and discharge of the solution. -The present invention contemplates a mechanical apparatus for stirring the solution in asimple, cheap, and extremelyeifective manner The nature'of the invention will be clearly understood from a description of the accompan'ying drawings, wherein- Figure 1 is a plan view of an electrolytic tank provided with the improvement. Fig. 2 is :a side elevation, partly in cross-section, at right angles to the anodes and cathodes. Fig? 3 is a cross-section on the plane 3 3 of Fig.j41. Fig. 4 is a detail of one form of vibrating mechanism for the improvement, and Figs'. 5 and 6 and 7 and Sare side and end views of two modifications.

Throughout the figures like reference-numerals refer tolike parts.

.The tank is numbered 10, and the anodes and cathodes are shown, respectively, at 11 and 12. These are usually suspended in parallel planes close to each other, as shown in the figures. Thelmeans of suspension of the anodes and cathodes and the electrical connections to them are omitted from the iigures, as they form no'part of my invention. p

The stirring mechanism preferably consists, as shown in Figs. 1, 2, 3, and 4, of the following elements: a reed.- board 15, sup,v ported at each end, so as to reciprocate preciselyi, provided with reeds 16, which extend I down between and parallel with the electrodes. The reed board is supportedv by means 'of sliding heads 17, which travel in guidew'ays .18 and are reciproeatedtherein by'means of cords or chains 19, running over rollers 2O and wheel 21,. Preferably the wheel 21 is a sprocket wheel whichV engages a sprocket-chain 22, secured to the cords or chains 19. The sprocket-wheel 21 is turned first in one direction and then in the other by means of a rack 30 and pinion 31. The reciprocation or vibration of the rack 30 turns the sprocket-wheel 21 in alternate directions, causing the .heads 17 and reed-board 15 to vi'- brate or reciprocate. By this means the reeds d,16 violently stir the electrolyte in the imme- Y diate Vicinity of the surface of the electrodes. Preferably there is one such stirring-reed on each side of every electrode or of all excepting the outer sides of the electrodes at the extreme ends. By this means stagnation of the solution is efl'ectuallyv prevented, also lumpy and loose deposits on the cathode as well as impure deposits. A very iine cathodesurface is deposited and the anode is conspmed ima remarkably regular and uniform manner. A great saving of scrap is effected and short circuits, likely to form by the accumulation of solid particles bridging across the space between neighboring anodes and cathodes, are positively prevented owing to the continual passage of the reeds to and fro..

In Figs. 5 and 6 the anodes and cathodes are omitted for clearness.' The reeds 116 are horizontal'and vibrate or reciprocate vertically. They are supported by rods 216,

which extend downward from the reed-board 115. The reedboard.115 is providedat each end with a slide 117, which vibrates vertically in the slideway 118 and is actuated by one or more cranks 130 and pitman 131. A pulley 132 may be employed to turn the crankshaft 133; I

In Figs. 7 and 8 the reed-board 215 rocks in bearings 315'instead of reciprocating. The reeds 16 therefore are vibrated or reciprocated transversely to their length angularly about the reed-boards 215 as an axis. crank 230 and pitman'-231 serve to rock the reed-board andactuate the stirring-reeds, as shown. i
